Max width

hey there,
so I finally come back to this. I started from Lorenzo's PR (https://github.com/chili-epfl/chilitags/pull/55), added a little test, and moved the resizing/preprocessing from FindQuad to the whole detection pipeline (otherwise our friend Refine takes infinite time too) : https://github.com/qbonnard/chilitags/tree/maxWidth
How about this one ?
